Angie Douthit, mother of "Teen Mom" star Mackenzie McKee, passed away on Monday, just days after announcing she was ending treatment for brain cancer, according to a post shared on her Instagram page.

"On Monday, December 9 at 11:37pm, Angie finished her race," read the caption posted Tuesday morning. "Her last days were spent lovingly surrounded by family and friends as they prayed, sang, and shared funny Angie stories."

Douthit was 50.

Last week, Douthit, who was diagnosed with stage 4 brain cancer in January 2018, shared that she would be seeking hospice care after finishing her radiation treatment.

"Today was a little rough," she wrote. "Scans showed results that were not good. The cancer has grown in the liver and in the brain. There is also some hemorrhaging in the brain. I will have two more doses of radiation and that will be the last treatment I will be given. I should be able to go home in the next few days. We have decided to have the hospice come in when I go home for some extra care."

Douthit was hospitalized the previous day, according to an Instagram post in which she described sudden dizziness.

A photo and caption posted over the weekend to Douthit's account by her family said, "Today has been a day full of love" and confirmed that Douthit was "hurting too much" to write the post herself.

"We thank you all for the love and generosity you have shown and continued to show," read the post. "Please continue to pray. She is hurting very badly and she is having trouble with her memory. She loves you all so much."

During an Instagram story shared on Dec. 6, McKee confirmed that her mother's condition "was not looking good." She also shared a sweet selfie of herself and her mother.

"I love you so much," she wrote, tagging her mother's Instagram account. McKee also shared that she had gotten a tattoo of the words "Always be kind" written on her arm in her mother's handwriting.

Douthit has been open about her illness, candidly talking about it on social media, on episodes of "Teen Mom OG" and in a book she penned titled "God's Plan" in which she detailed her journey.

"She wasn't able to sleep an entire night so she would wake up around 3am to write her posts," read the message posted Tuesday morning. "We watched her get up every day in the darkest hours of the night to spread the brightest light that she knew of, her Savior Jesus Christ. There were times when she wrote her posts through pain and confusion. There were times at the end when she couldn’t type and would ask her daughters to type for her but she would not give up spreading the gospel message of hope. In nearly two years, she never missed her daily post ... tomorrow she will."
